norse.torch.module.conv.LConv2d

class norse.torch.module.conv.LConv2d(in_channels: int, out_channels: int, kernel_size: int | Tuple[int, int], stride: int | Tuple[int, int] = 1, padding: int | Tuple[int, int] = 0, dilation: int | Tuple[int, int] = 1, groups: int = 1, device=None, dtype=None)

Implements a 2d-convolution applied pointwise in time. See https://pytorch.org/docs/stable/generated/torch.nn.Conv2d.html?highlight=conv2d#torch.nn.Conv2d, for documentation of the arguments, which we will reproduce in part here.

This module expects an additional temporal dimension in the tensor it is passed, that is in the notation in the documentation referenced above, it turns in the simplest case a tensor with input shape \((T, N, C_{ ext{in}}, H, W)\) and output tensor of shape \((T, N, C_{ ext{out}}, H_{ ext{out}}, W_{ ext{out}})\), by applying a 2d convolution operation pointwise along the time-direction, with T denoting the number of time steps.

{groups_note}

The parameters kernel_size, stride, padding, dilation can either be:

• a single int – in which case the same value is used for the height and width dimension

• a tuple of two ints – in which case, the first int is used for the height dimension,

  and the second int for the width dimension

Args:

in_channels (int): Number of channels in the input image out_channels (int): Number of channels produced by the convolution kernel_size (int or tuple): Size of the convolving kernel stride (int or tuple, optional): Stride of the convolution. Default: 1 padding (int, tuple or str, optional): Padding added to all four sides of

the input. Default: 0

dilation (int or tuple, optional): Spacing between kernel elements. Default: 1 groups (int, optional): Number of blocked connections from input

channels to output channels. Default: 1

__init__(in_channels: int, out_channels: int, kernel_size: int | Tuple[int, int], stride: int | Tuple[int, int] = 1, padding: int | Tuple[int, int] = 0, dilation: int | Tuple[int, int] = 1, groups: int = 1, device=None, dtype=None)
